Abstract:
Please note that a newer version of this dataset is available (https://doi.org/10.1594/PANGAEA.958978)!
This is version 2.0 of MARHYS (MARine HYdrothermal Solutions) database.
For general information about the database, check out the initial publication Diehl & Bach, 2020 (https://doi.org/10.1029/2020GC009385) and Version 1.0 of the database (https://doi.org/10.1594/PANGAEA.921794).
In brief, following changes have applied in the course of compilation of MARHYS database version 2.0:
-A large number of new vent sites from following regions is now incorporated in the database: southern Mid Atlantic Ridge, Arctic Mid Ocean Ridge, Juan de Fuca Ridge, Okinawa Trough, Lau Basin, Manus Basin, and some more (The database has grown about nearly 50% and now contains 3394 merged entries, compared to 2374 merged entries in Version 1.0).
-The complete sample information section for a larger number of entries was overhauled to achieve more consistency between different datasets and within individual vent sites (additional Sample ID's have been adjusted to fit the database naming scheme and to ensure unique sample entries).
-Some new species were included.
-A small number of faulty concentrations were detected and corrected.
-A number of vent areas in the Manus Basin were erroneously classified in Version 1.0 and are now re-classified as back-arc spreading centers (Susu, Desmos, PACMANUS).
-The shape of the spreadsheet was improved by freezing the "Sample ID" column, as well as, the parameter and unit rows to provide users more comfort when browsing the database.
-The built-in Excel filter function is now turned on by default (row 14) and enables users to easier generate sub-datasets of interest.
-A complete reference list of the database Version 1.0 can be found in Diehl & Bach, 2020. To provide an updated reference list, the data files given below are complemented by the Word file MARHYS_DB_2_0_ReferenceList.docx.
The main file containing the final product is:
MARHYS_DB_2_0.xlsx
The remaining files are provided to be able to track the processing of the data:
MARHYS_DB_2_0_Rawdata.xlsx provides a one-by-one copy of the single datasets as provided in the original source.
MARHYS_DB_2_0_RawdataConverted.xlsx provides a one-by-one copy of the single datasets with converted units.
MARHYS_DB_2_0_Unmerged.xlsx provides the data in the format of MARHYS Database without sample entries being merged.
MARHYS_DB_2_0_MergeHistory.xlsx provides a list of all sample entries that were merged.
MARHYS_DB_2_0_ReferenceList.docx provides a list of all sample entries that were merged.
Please note: We encourage users of the database to also cite the original literature whenever possible. If you want to adress any inquiries about the database do not hesitate to contact the support center (marhys@uni-bremen.de). The database is an ongoing project and will be updated twice a year.
The data files and reference list are exclusively provided as Excel sheets/Word file and show up when clicking view dataset as html below.
